As a word: "sudo" as in "judo" (or "Ludo"). And the word "dew" is 'dyu', at first approximation and given that I'm too lazy to dig up yer'actual IPA symbols for that.

And "radar" is 'ray dah' mostly because 'rad ah' would be pronouncing something like "raddar", certainly once it has become a word in its own right, while I'm at it. But if you want to reduce it to "Ray Dee Aye Ar" (changing nothing in the first syllable) you can also capitalise it as "RaDAR" while you're at it.

I wanted to chip in that whenever I use "pseudo", it feels like I'm asking the computer to pretend I'm someone I'm not, and the situation is fake and temporary, in spite of the typically dramatic consequences.
